Filed: 1970-08-11
Abstract: 1288324 Digital data storage BURROUGHS CORP 11 Aug 1970 [15 Oct 1969] 38556/70 Headings G4A and G4C A digital electric data handling system comprises a movable storage medium having a data track and a clock track, and a digital computer programed to generate data for recording on the data track at an appropriate time. The storage medium is preferably a magnetic disc though it could be any movable medium which need not rotate, move at constant speed, or move continuously and the data is address data. The disc (Fig. 1, not shown) has a clock track, an address track and a data zone, and a read head recovers clock pulses therefrom (Fig. 4A), the pulses being evenly spaced along the track apart from periodic gaps. After a gap the first clock pulse starts the computer which executes an LBT instruction (Fig. 4C) which causes a counter to count a predetermined number of pulses. A number of instructions A to Z which compute the first address are then executed and the computer halted. When the counter has finished counting the computer restarts, the first address is transferred to a shift register in parallel, recorded on the disc in series by an LSR instruction, and the cycle repeated for the next address. In a modification (Fig. 5, not shown) the addresses can be recorded at a lower density than the clock data without changing the computer operation speed. A computer program for calculating the addresses is described (Fig. 2, not shown) and includes conditional branch instructions. The computer includes a read only memory section with replaceable memory cards, each card holding the program for a different address format so the computer can be modified for any address format.

Abstract: 1498349 Rotary drum driers CREUSOT LOIRE 17 Sept 1976 [8 Oct 1975] 38707/76 Heading F4G [Also in Division B1] An inclined rotary drum mixer for coated products (e.g. concrete or hot or cold bitumen/ aggregate mixtures) has a first zone 25 with non-mixing helical blades 30, a second zone 26 having lifting devices 30-32 of cross-section of constantly increasing curvature, and a third zone 27 with lifting devices of constant curvature equal to that at the outlet of the second zone; there may also be a discharge zone 28 which is smooth or has ribs 33, and a burner 14 (which is not used for cold mixing) at the inlet end of the drum. A liquid (e.g. water, or bitumen, or cold bitumen emulsion) is fed by pipe 16 to the entrance to the third zone 27; the apparatus discharges into a fixed chamber 20. Aggregate and powdery material are fed by a belt conveyer 12, the apparatus may be arranged for transport as a semi-trailer and the conveyer stored beneath the drum, (see Figs. 6 and 7, not shown). At the end of the second zone 26 material is lifted to the highest point of the drum and forms a curtain which shields the zone 27 from the burner; there may be a screen 34 to prevent the escape of dust from the drum.  The apparatus may be automatically controlled so that the supply of liquid and of powdery material is in dependence on a gravi. metric detector associated with conveyer 12; the water content of the aggregate may control the rate of supply of liquid; and the positions of the end of the pipe 16 may be automatically adjusted in dependence and the smoke density of the gases discharged as measured by an opacimeter in the flue 22. Thus the output may be varied while maintaining constant ratio of the constituents merely by varying the rate of supply of the aggregate.

Title: Improvements in or relating to the wrapping of articles
IPC: B65B19/22
Filed: 1957-12-13
Abstract: 831,628. Wrapping machines. SCHMERMUND, A., [trading as MACHINENFABRIK A. SCHMERMUND]. Dec. 13, 1957 [Oct. 18, 1957], No. 38812/57. Class 94(1). In a machine in which a composite wrapper, comprising overlapping portions of different lengths, is folded around an article such as a batch of cigarettes, a web W 1  is fed from a roll 40 by driven roller 1, 2 and passes downwardly between guides 42, 43 and 28, 29, and a second web W 2  is simultaneously fed from a roll 41 by slower, driven rollers 3, 4 and passes over a roller 5 and guide 44 into alignment with the web W 1  When the leading end of the latter has reached a stop 45, the two webs are severed simultaneously by cam-operated shears 6, 7 to form two strips of unequal lengths having their trailing edges coincident. The shorter strip is then held by a suction device 17 while the longer strip is engaged by an article W 3  which is moved forwardly by a pusher 24 on an endless chain 25. The article carries the strip into a folding channel defined by a table 16 and an endless belt 9 passing under a plate 13 and around rollers 8, 10, 11, 12, 14 and 15, thus causing the strip to be folded in the form of a U and its upper end to be moved downwardly relative to the stationary shorter strip. When the required overlap between the strips has been produced, the device 17 releases its grip and an endless belt 46 driven at the same speed as the chain 25 is moved to the left. The two strips are thus gripped between the two belts and a drive is transmitted to the belt 9 so that the overlap is maintained while the folding of the wrapper to U-shape is completed. The belt 46 passes around collars 18, 19 and 47 carried by a parallelogram linkage 20-22 actuated by a cam 27. A wedge 48 deflects the leading end of the shorter strip to ensure that it passes between the article and the belt 9.

Title: Process for the manufacture of vanadium oxide
IPC: C01G31/00
Filed: 1964-09-24
Abstract: Vanadium oxide, V2O5, is recovered by extracting an aqueous solution containing dissolved salts of vanadium of valency 5 with a water-immiscible organic solution containing a water-insoluble aliphatic tertiary amine salt or quaternary ammonium salt to form an aminevanadium organic complex in the organic phase, separating the organic phase from the aqueous phase, stripping the vanadium from the organic phase by treatment with a stripping solution containing ammonia and ammonium chloride to form a 3-phase mixture comprising an organic phase, an aqueous phase and a solid phase, the amount of NH4Cl being at least 9% in excess of the amount required to form ammonium metavanadate from the said complex and the amount of NH3 being sufficient to maintain a pH of at least 8 in the aqueous phase, whereby ammonium metavanadate is precipitated as the solid phase in the aqueous phase, separating this aqueous phase containing NH4VO3 from the organic phase and converting the NH4VO3 to V2O5.  In one embodiment, ground vanadium ore or concentrate is roasted with an alkali metal salt, e.g. NaCl, and the roasted solids are leached with water.  The leach solution is mixed with a solution of the amine salt, in which the alkyl groups may contain 8 to 20 carbon atoms, or of the quaternary ammonium salt obtained by methylation of such an amine salt, in kerosene or fuel oil and the resulting organic phase may be washed with aqueous NH3 to remove phosphorus values, prior to treatment with the NH4Cl/NH3 stripping solution.  The aqueous phase containing solid NH4VO3 is separated from the organic phase, which is recycled, and the NH4VO3 crystals recovered by filtration from the aqueous phase, which is also recycled.  The NH4VO3, optionally together with NH4F to remove any silicon present, is dried and marketed as such, or it may be heated to form V2O5 by expulsion of NH3, which is scrubbed with water, the resulting solution being used to scrub the gases from the roasting stage and thus produce the required NH4Cl/NH3 solution. The V2O5 may be passed to a fusion furnace to form pure fused V2O5.  Reference has been directed by the Comptroller to the Specification 907,465.
